No. 851,195. Patented. April 23, 1907.

To all whom it may concern:

1 Be it known that we, ALBERT L. BAUER and RAYMUND BAUER, citizens ofthe United Fig. 7 illustrates a slight modification of the i abutment.

' Similar numerals of reference are employed States, residing atWheeling, in the county of to indicate corresponding dparts throughout.Ohio and State of West Virginia, have inthe several figures of the rvented a new and useful Engine, of which the i awings. In carrying outthe invention, two engines following is a specification. i of similarconstruction are connected to a This invention relates to rotaryengines, main shaft 10, and the engines operated in and has for itsprincipal object to provide a 1 consecutive order, one eliecting a halfrevonovel form of engine in which a cylinder is lutlon of the shaft,whlle the other efiects the second half revolution, so that both pistonsmay make the complete rotation.

The cylinder 11 of each engine is circular in form, and within saidcylinder is a circular piston drum 12, rigidly secured to the shaftlOand carrying a radially disposed piston wing 13, Which 'travels in theannular space between the periphery of the piston drum and the innercircular wall of the cylinder. Arranged above, and in communicationwithpart displaced by the action of-a fluid under pressure, or by theformation or combustion of a gas or other compound, the water serving totransmit movement to the revoluble piston and preventing direct contactbetween the piston and the actuating fluid.

A further object of the-invention is to provide a rotary engine in whichthe force or pressure of the fluid actuating medium is transmitted tothe piston through the medium of a liquid.

A still further obj ect of the invention is to provide a novel form ofrotary engine in which the cylinder is arranged in communication yvith apair of chambers, either of which may serve as the compression cham:ber, while the other receives a volume of liquid equal to that displacedby the action of thefluid.

With these and other objects in view, as

of vertically disposed casings -15 and 16, and between these casings isa movable abutment 17. This abutment may be moved to such position astopermit the free passage of the piston wing 13 as the piston drum 12rotates.

'The cylinder and the chambers 15 and 16 are filled with water or otherfluid up to the level indicated in Fig. 1, and where steam or similarfluid is to be employed as the working in each of the cham em 15 and 16,t e piston serving to prevent direct contact between the steam and theWater, thus avoiding unnecessary condensation. P p

The cubic content of each of the chambers 15 and 16 is approximatelyequal to the cubic content of the annular space between the piston drumand the inner clrcular Wall of the cylinder, and when .the steam orother fluid is operating in one of said chambers, the li uid displacedby the action ofthe steam will rise in the other chamber.

At a short distance above the normal level tion consists in certain novefeatures-of construction and arrangement of parts, hereinafter fullydescribed, illustrated in the pointe out in the appended claims, itbeing understood that various changes in the form, proportions, size andminor details of the structure. may be made without departing vantages othe invention. I

Fig.3 is aplan view of the engine, parts being broken away to more clearlyillustrate the abutment connectionsj Fig. 4 is a sectional plan viewthrough' the lane of the adjustable valve or abutment o the expan- 1sion chambers. Fig. 5 is a sectional plan view through one of the valvesfor control valve or abutment 22 which ma be moved across one or otherof the cham ers 15 and sion or pressure space, the opposite wal beingformed by one of the floating istons, and when this slidable valve 'or autment is fluid.

is displaced.

The adjacent Walls of the two cylinders are 16 in order to form one wallof anex an the upper portion of the cylinder 11 is a pair -medium, afloating iston 19is arran ed'withof the floating piston, 19 is arrangeda slidable moved across one of the chambers, it leaves the other chamberwholly clear, 'so that the floating piston may freely rise as the wateror abutment 22, which will occur at-a timewhen the abutment 17 is downin engage ment with .the peripheryof the piston 12 and the piston '13has moved to about the position shown in Fig. 1, the ressure and exansive force of the steam will depress the oat' ing piston 19, and thismovement will be transmitted through the water or other liquid,compelling the piston wing to move in the direction indicated by thearrow and the liquid ahead of the piston wing will be forced tomoveupward into the chamber 16.

The volume of liquid\ normally contained within the chamber 15 isslightly greater than half the volume of fluid'in the'annular spacebetween the piston drum and cylinder,

so that by the time the floating piston 19 has completed its stroke, theiston drum will have made a'one-half revo ution, and practically all ofthe water will be displaced from chamber. 15, while the chamber 16 willbe nearly full. At this stage of the operation, the second engineof theshaft 10 will operate, the piston 13' of the second engine being at a'point diametrically op osite the piston 13 of the first engine, and t ssecond engine will compelthe second half revolution of bothpistons. isadmitted to the second engine, the abut+ ment 17 of the first engine ismoved from the annular space surrounding the piston and the exhaustvalve below the valve or abutment 22 is open, so that the liquid'in thetwo chambers 15 and 16 may assume a common,

level, and this levelwill have been attained vbythe time the piston wing13 a ain reaches the position shown in Fig. 1, and

is in readiness to commence a second, stroke, or second rotation. v

The abutment 17 is preferably formed of two segmental plates 28 that arepivoted on shafts 29 and 30, these shafts being providedv with reducedend portions havingintermeshing gears 31 to insure simultaneous movementof the abutment members to open and closed position. of the abutmentmembers are arranged to fit against the correspondingly concaved surfaceof the piston drum 12, and when in 1 closed positionthe abutment issufliciently' tight to prevent the leakage of the li uid from one sideof the cylinder to the ot ier. One of the shafts, 29 .-is providedwith aImmediately after the steam gear with its pin 42.

The curved outer ends rocker arm 33, which is connected to one end of alever '34 that is pivoted on a bracket 35 carried by the frame, and thislever 34 is pivoted at a point intermediate of its ends to a verticallymovable bar 37 thatis'und'er the controlof a cam- 38 carried by the mainshaft.

When the actuating fluid is not-ofsuc'n-n'a ture asto rapidly condensewhen brought into contact with liquid, the floating pistons 19 may bedispensed with and the fluid allowed. to operate directly against thewater or other liquid. For this purpose compressed air or an explosivecompound may be employed, and the upper ends of the chambers. 15 and 16'may be laced in-communication with each other, t us ermitting theemployment of chambers of ess height than where the:floating pistons areused. The liquid displaced from the lower portion of one chamber is.then free to flow'upward into the second chamber, while the space abovethe valve or abutment in the first chamber serves toreceive the airabove the fluid, which air being placed under slight pressure, will tendto assist in restoring the normal level of the water after the abutments17 have been moved to open position. i

In some, cases the abutment may be formed of a single. plate 17 and'inthis case provision must be made for a greater range of movement of theabutment, than where in the preferred construction.

The valves 26 are provided with stems 40 from which extend hooks 41 thatengage ins 42 carried by the bell crank levers 43. he bel crank leversare pivoted to brackets 44, projecting from the'fiame of "the engine,and said bell crank levers are connected by rods 45 to eccentrics 46 onthe main ,shaft.

To provide for the reversal of the engine, a shaft 47 is carried by thebrackets 44 and to said shaft is secured a pair of cams 48, and the camsof eachpair or 'set are disposed at a right angle to each other. Attheend of-the shaft is an operating lever 50 which may be turned for thelpurpose ofthrowing one hook out of gear wit the pin 42, while the hookof the mating valve is allowed to drop into This aflords a central meansfor disconnecting the valves of .those oint above the liquid level,whereby the iquid in said chamber is displaced and the movementtransmitted to the piston wing.

In a rotary engine, the combination with a cylinder, of a pair ofliquid containing chambers in communication therewith, a revoluble'iston drum, a piston wing extending there rom, an abutment movable intoand out of the path of the piston wing to per mit communication betweensaid chambers, means for controlling the admission and exhaust of anoperating fluid to one or other of the chambers at .a oint above theliquid level, whereby the liquid may be displaced from one chamber andrise in the other, and

' transmit movement to the piston wing.

I The combination ina rotary engine, of a cylinder, a pair ofvertically disposed liquid containing chambers in communicationtherewith,.a-mo vablevalve or abutment adjustable across either of thechambers and forming the fixed wall of a pressure space, a valvecontrolling the admission and exhaust of fluid under pressure to thispressure space, a piston drum, a wing projecting therefrom;

an abutment, and means for moving the abutment into and out ofengagement with said piston drum. i

4. The combination in a rotary engine, of a cylinder, a pair ofvertically disposed liquid containing chambers in communicationtherewith, float istons arranged within the charmbers, a sli able valveor abutment movable across either of the chambers to form one wall of apressure space, a valve for controlling the admission and exhaust of aworking fluid to the pressure space, a piston drum in' the cylinder, apiston wing carried by the drum, an abutment, and means for actuatingthe abutment.

5. In a rotary engine, the combination with a shaft, of a pair ofcylinders surrounding the same, a air of piston drums secured to theshaft and aving piston wings, the wing of one drumbeing diametricallyopposite the wing of the other drum, a air of iquid containing chambersconnecte to each cylinder, means for introducing a fluid under ressureto one chamber of each pair to disp ace the liquid therein, theoperations alternating in the respective chambers, and abutments movableinto and from the cylinders to permit communication between the liquidcontaining chambers ofeach pair.
